*Jack’s 321 is a tried and true two-part fertilizer program. It consists of Jack’s Nutrients Part A 5-12-26, Jack’s Nutrients Part B 15-0-0 and Epsom Salts. BUT where does that “321” come from, you ask? It’s the shortened amount of each fertilizer in grams per gallon. To mix up the perfect blend of Jack’s 321 you will need 3.6 grams Part A 2.4 grams Part B 1.2 grams of Epsom salts . This will give you a blend of nutrients for growing almost any controlled environment crop, in any growing system. The order of additions is VERY important. You must add the 5-12-26 first and make sure it is completely dissolved, then add in the Epsom salts making sure it is completely dissolved, then finally the calcium nitrate. In addition to these three nutrients, 2oz. of Haifa MKP (monopotassium sulphate) have been included to give you an amazing Bloom Boost nutrient for your fruiting and flowering plants as well as a FREE recipe for different strengths and necessary mixing orders.
